Recent Grafana Labs Security Vulnerabilities

CVE	Date	Vulnerability	Products
CVE-2026-33379	Nov 06, 2026	Grafana 12.4 Dashboard Snapshot Auth Bypass A user with any role, including Viewer or a service account with no permissions, can create, externally publish, and delete dashboard snapshots (missing authorization). Only Grafana OSS and Grafana Enterprise 12.4 are affected; earlier versions and Grafana 13 are not.	Grafana
CVE-2026-81938	Nov 02, 2026	Grafana Mimir Alertmanager Local File Disclosure via HTTP Header Config - pre-3.1.7/3.2.2 Grafana Mimir's Alertmanager rejects tenant-supplied receiver configurations that reference local files, but the check did not cover two HTTP client settings: http_headers.<name>.files and basic_auth.username_file. A tenant permitted to upload an Alertmanager configuration could point these fields at any file readable by the Alertmanager process. When a notification was sent, Alertmanager read the file and put its contents in a header of the outgoing request. By directing the receiver at a server they control, the tenant could read files from the Alertmanager host, such as credentials and configuration. Exploitation requires permission to write the tenant's Alertmanager configuration. Grafana Enterprise Metrics (GEM), which is built on Mimir, is also affected. The issue is fixed in Mimir 3.1.7 and 3.2.2 and in GEM 2.17.20. GEM 2.11 through 2.16 will not receive a fix; users on those versions should upgrade to 2.17.20 or later.	Enterprise Metrics Grafana
CVE-2026-79656	Oct 28, 2026	Grafana Log Leak of OAuth/ID Tokens via Unredacted Logging A user with read access to Grafana's server logs, or to a log store they are shipped to, can recover the OAuth and OIDC access, refresh and ID tokens of users who sign in through the Generic OAuth, Google or GitLab providers. Grafana writes these tokens to its logs unredacted when an access or ID token is not a valid JWT, when the ID token is missing (at debug level) or is not a string (exposure of sensitive information in log files). The exposure is bounded by the scopes granted to the configured OAuth client.	Grafana
CVE-2026-103506	Oct 28, 2026	Grafana13.2 AuthBypass: SSO client secrets read/modify via k8sSsoApi An authenticated user in Grafana can read SSO client secrets and modify instance-wide SSO settings without the required permissions (missing authorization). This affects Grafana OSS and Enterprise 13.2 installations with the experimental kubernetesSsoSettingsApi feature toggle enabled, which is disabled by default.	Grafana
CVE-2026-88858	Oct 28, 2026	Grafana Viewer Recursion Crash via Math Expression A user with the Viewer role in Grafana can crash the server by submitting a crafted server-side math expression (uncontrolled recursion). A user with permission to provision alert rules can make the outage persist across restarts.	Grafana
CVE-2026-88967	Oct 28, 2026	Grafana Azure Monitor Data Source SSRF Exposes Azure Access Token A user with query access to an Azure Monitor data source in Grafana can cause server-side requests to an attacker-controlled endpoint that disclose the data source's Azure access token (server-side request forgery).	Grafana
CVE-2026-100105	Oct 28, 2026	Grafana Contact Point Privilege Escalation via Legacy Schema A user with permission to edit contact points but not their protected fields can change protected settings, such as a contact point's destination URL, by switching an integration to a legacy schema version, which can expose stored credentials and redirect alert notifications (incorrect authorization).	Grafana
CVE-2026-16491	Oct 27, 2026	Grafana RBAC Service Ignores Folder for Deleted Dashboard (CVE-2026-16491) Grafanas RBAC service ignored the requested folder when checking whether a user was a folder administrator for deleted dashboard listings. A user with dashboard permission-management rights on any folder could therefore be treated as an administrator of every folder. This could expose deleted dashboard items from folders where the user lacked administrative access. The fix requires permission on the specified folder, an ancestor, or a wildcard scope.	Grafana
CVE-2026-92539	Oct 20, 2026	Grafana Enterprise SCIM IDOR crossorg user edits A service account with user-management permissions in one organization can read, modify, disable or delete users belonging to other organizations on the same Grafana instance through the SCIM API (insecure direct object reference). Only Grafana Enterprise instances with SCIM enabled are affected.	Grafana
CVE-2026-9703	Oct 15, 2026	Grafana Data Source Proxy Bypass RCE: Viewer Role Can Modify Loki Rules Grafana's data source proxy did not apply role-based access control to write requests forwarded to Loki data sources. A user holding only the Viewer role on an affected Grafana instance could send POST, PUT and DELETE requests through the proxy to the Loki rules API (/loki/api/v1/rules), allowing them to create, modify and delete Loki alerting rules. Because those rules are stored by Loki rather than by Grafana, the change took effect for every user of that Loki data source, not only for the Viewer who made the request. Exploitation requires an authenticated Viewer account on the Grafana instance and a configured Loki data source; no other privileges are needed. Both Grafana OSS and Grafana Enterprise are affected. The defect is in Grafana's data source proxy; Loki itself is not vulnerable and does not need to be patched.	Grafana
CVE-2026-95502	Oct 13, 2026	Grafana Git Sync Uncontrolled Resource Consumption (Memory Exhaustion) A Git server that Grafana's Git Sync (provisioning) is configured to use can exhaust Grafana's memory by returning oversized or highly compressed responses (uncontrolled resource consumption). Exploitation requires an administrator to have configured Git Sync with that server.	Grafana
CVE-2026-93294	Oct 13, 2026	Grafana Azure Monitor Data Source Proxy Escalation via Unintended Identity A user with query access to an Azure Monitor data source can use its resource proxy to call Azure Resource Manager APIs beyond those Grafana needs, with the data source's Azure identity (unintended proxy). The impact is bounded by the Azure role granted to that identity.	Grafana
CVE-2026-33374	Oct 13, 2026	Grafana Unbounded Memory Allocation via Prometheus Rule Conversion API The Prometheus rule conversion API endpoints in Grafana do not limit request body size, allowing authenticated users to trigger unbounded memory allocations that can crash the server through out-of-memory conditions.	Grafana
CVE-2026-15577	Oct 13, 2026	Grafana 12.4 R/O User Overwrites Conn Conf via Status Subresource A user or service account with read-only access to Git Sync (provisioning) connections can modify a connection's configuration through its status subresource (incorrect authorization). On Grafana 12.4 the affected API is only available when the experimental provisioning feature toggle is enabled.	Grafana
CVE-2026-89039	Oct 05, 2026	Grafana k6 v0.3.0+ File Path Disclosure via convert_playwright_script Prompt A caller who can invoke the convert_playwright_script prompt in mcp-k6 can pass a bare file path as the playwright_script argument and receive the contents of any file readable by the user running the server, including SSH keys and cloud credentials in that user's home directory (path traversal). The working-directory restriction applied to '@'-prefixed paths can also be bypassed with a symbolic link inside the working directory that points outside it.
CVE-2026-13720	Sep 30, 2026	Grafana Dashboard API Allows Unauthorized FileProvisioning Metadata Injection An Editor can set file-provisioning metadata (the grafana.app/managedBy, grafana.app/managerId and grafana.app/sourcePath annotations) when creating a dashboard through the dashboard API, because these fields were stored without an authorization check. The dashboard then appears file-provisioned, and administrators can no longer update or delete it through Grafana. The impact is limited to the same organization and no data is exposed.	Grafana
CVE-2026-13719	Sep 30, 2026	Grafana 13.1.0 Alert Rules API Info Exposure via Folder Filter An authenticated user can list alert rules stored in folders they are not allowed to read through the alert rules API list endpoint. When the set of folders the user may read was empty, the folder restriction was dropped and every alert rule in the organization was returned. From Grafana 13.1.0, any user can trigger this with a folder filter. The exposed data is rule configuration; data source credentials are not exposed.	Grafana
CVE-2026-81842	Sep 29, 2026	Grafana Library Panel AuthZ Bypass via Folder Move API An authenticated user with edit permission on one folder can move a library panel into another folder where they only have view permission, through the library elements API or the equivalent App Platform resource. The update path did not check library panel create permission on the destination folder (incorrect authorization). No data from the destination folder is disclosed, and existing content there cannot be changed.	Grafana
CVE-2026-81841	Sep 29, 2026	Grafana Paused Dashboard Auth Bypass via Unrevoked Access Token - CVE-2026-81841 Pausing a shared (public) dashboard did not revoke its access token for the endpoints that serve frontend bootstrap data. Anyone holding the link to a paused shared dashboard could still retrieve, without authenticating, the configuration of the dashboard's data sources, including stored credentials for data sources using browser access (missing authorization). Deleting the shared dashboard does revoke the token.	Grafana
CVE-2026-15815	Sep 17, 2026	Grafana RCE via Unsafe Plugin Archive Extraction (CVE-2026-15815) Grafana OSS and Grafana Enterprise did not safely resolve symbolic links when extracting plugin archives. A crafted plugin archive can chain relative symbolic link entries to escape the plugin installation directory, writing arbitrary files and an executable backend binary outside that directory. The dropped executable runs with the privileges of the Grafana server process, resulting in remote code execution. Plugin archives are extracted before their signature is verified, so a valid plugin signature does not prevent the write. An operator can therefore be affected by installing a plugin that appears legitimate, as well as by installing a plugin from an arbitrary archive using grafana-cli, the GF_INSTALL_PLUGINS environment variable, or preinstall configuration. Grafana Enterprise is affected because it includes the same plugin extraction code as Grafana OSS.	Grafana
CVE-2026-76154	Sep 17, 2026	Grafana GeoMap Panel XSS in MapLibre Base Layer Escalation A stored cross-site scripting vulnerability in the Geomap panel's MapLibre base layer allows a user with the Editor role to execute arbitrary JavaScript in another user's session by hosting a malicious style configuration, enabling escalation to Org Admin.	Grafana
CVE-2026-14199	Sep 02, 2026	Auth Proxy Cache Key Collision in Grafana Allows Auth Bypass (CVE202614199) Only self-managed Grafana instances with Auth Proxy authentication and identity caching enabled (sync_ttl greater than zero) are affected. The Auth Proxy cache key concatenated the username and forwarded identity attributes without a delimiter, so distinct identities could collide on one key. An authenticated user who shapes their own attributes to collide with a higher-privileged user's, while that user's cache entry is live, is authenticated as that user, up to Administrator (authentication bypass by spoofing).	Grafana
CVE-2026-12704	Sep 02, 2026	Grafana Enterprise SAML Replay Vulnerability via InResponseTo Skip When SAML IdP-initiated login is enabled in Grafana Enterprise, the SAML library skips validation of the InResponseTo field on all SAML responses, including SP-initiated logins. This removes anti-replay protection, allowing an attacker who obtains a valid signed SAML assertion to replay it and gain a session as the victim user. Only instances with the allow_idp_initiated SAML setting enabled are affected; this setting is off by default and Grafana OSS is not affected.	Grafana
CVE-2026-19475	Sep 02, 2026	Grafana Denial-of-Service via SQL Macro Injection An authenticated user with permission to query a SQL data source can bypass the fix for CVE-2026-33375 by injecting the timeGroup macro through a WHERE clause, which Grafana's regex-based macro parsing does not reject. Evaluating the injected macro causes uncontrolled memory consumption that can terminate the Grafana server process, resulting in a denial of service. The Microsoft SQL Server, PostgreSQL, and MySQL data sources are affected.	Grafana
CVE-2026-75889	Aug 27, 2026	Grafana Alloys ServiceMonitor bearerTokenFile LFD Grafana Alloys prometheus.operator.servicemonitors component allows a user who can create or modify ServiceMonitor resources in a watched namespace to specify an arbitrary local file through bearerTokenFile. Alloy reads the file and sends its contents as a bearer token to an attacker-controlled scrape endpoint. This may disclose files accessible to the Alloy process, including its projected Kubernetes service account token, potentially granting the attacker Alloys Kubernetes permissions. Exploitation requires ServiceMonitor write access and lower privileges than Alloys service account.
CVE-2026-19854	Aug 27, 2026	Grafana ClickHouse Plugin TLS Bypass via PDC/secure SOCKS When the ClickHouse plugin uses Native protocol (the default) with PDC or secure SOCKS, it asks for TLS but the connection library ignores that and talks to ClickHouse in the clear. Username, password, queries, and results can be read on the hop after the proxy. The server certificate is never checked, and a configured client certificate is not sent.
CVE-2026-19197	Aug 26, 2026	Grafana: Insecure Deletion of CrossOrg Dashboard Snapshots (CVE202619197) A user with organization administrator permissions can delete dashboard snapshots belonging to other organizations on the same Grafana instance, and can recover a snapshot's secret delete key using only its public share key (broken access control).	Grafana
CVE-2026-17033	Aug 24, 2026	Grafana XSS via alert.generatorURL in external Alertmanager alerts An authenticated attacker with Editor access or alert.instances.external:write can submit an external Alertmanager alert containing a controlled generatorURL. The attacker is authorized to create the alert, but not to execute script in another user's Grafana session. Grafana renders alert.generatorURL directly as the Alert Details See source LinkButton href without URL-scheme sanitization or a safe-protocol allowlist. The click interceptor's :// heuristic can be bypassed by placing :// inside a JavaScript comment. When a user with read access clicks See source, the browser executes attacker-controlled JavaScript in the Grafana origin with the clicking user's permissions.	Grafana
CVE-2026-17183	Aug 19, 2026	Grafana Alert Rule Query Auth Bypass via SSR An authenticated user with permission to create or edit alert rules can bypass datasource query authorization by marking an alert rule query as a server-side expression while referencing a real datasource UID (incorrect authorization). This can expose data accessible through Grafana's configured datasource credentials to users who lack permission to query that datasource.	Grafana
CVE-2026-11817	Aug 17, 2026	Grafana Cross-Org Info Disclosure via /api/access-control This vulnerability only affects Grafana stacks configured with multiple organizations; single-organization deployments are not impacted. In a multi-organization stack, a user who is an Org Admin of a single organization can call GET /api/access-control/users/permissions/search?actionPrefix=dashboards: and receive permission data belonging to other organizations. The disclosed data is limited to dashboard and folder identifiers (UIDs) and per-user permission/scope mappings (which user holds which access on which dashboard). Dashboard contents, panels, query results, datasource credentials, secrets, and personal data are not exposed. This is a limited cross-organization information disclosure affecting multi-org deployments only.	Grafana
CVE-2026-19516	Aug 11, 2026	SSR In Grafana mcp-grafana via X-Grafana-URL Header A caller-supplied X-Grafana-URL request header controls the destination of mcp-grafana's outbound requests, and the grafana_api_request tool lets the caller also choose the HTTP method, path, and body. Because the destination is not restricted to the configured Grafana instance, a caller can direct requests at internal, loopback, and link-local network services (including metadata endpoints) and read the responses, resulting in server-side request forgery. The fix for CVE-2026-15583 prevented the configured service-account token from being sent to unintended destinations but did not restrict the destinations themselves.	Grafana
CVE-2026-72585	Aug 10, 2026	Grafana <=13.2.0 Editor Bypass Deleting Protected Contact Points	Grafana
CVE-2026-9765	Jul 24, 2026	Grafana Access Control Bypass (CVE-2026-9765) Note: The CVE and blog post don't exist because we determined this is actually a cloud-only issue. Access Controls are Broken when a user can access resources they are not authorized to access. An attacker can bypass any access control mechanisms in a web application, and gain unauthorized access to resources that are not available with their permissions. Broken access control can allow attackers to: Access resources only accessible to certain users, thus allowing unauthorized access to data Perform operations on behalf of other users, leading to account takeovers in the worst cases Attempt privilege escalation Attempt to take over an account	Grafana
CVE-2026-21723	Jul 23, 2026	Grafana Alertmanager Templates OOM via Unlimited Exec The alertmanager templates test endpoint (/api/alertmanager/grafana/config/api/v1/templates/test) can execute templates with no memory limits. Mass-executing templates in a short period causes OOM and crashes the Grafana service. The endpoint requires very low privileges and is exploitable with anonymous access enabled.	Grafana
CVE-2026-21729	Jul 16, 2026	Loki large limits memory alloc DoS Loki queries with large limits can cause large memory allocations which can impact the availability of the service, depending on its deployment strategy.
CVE-2026-15583	Jul 15, 2026	Unauthenticated Exfiltration via Confused-Deputy in Grafana MCP Server A confused-deputy flaw in Grafana MCP Server allows an unauthenticated remote attacker to exfiltrate the server's environment-configured Grafana service-account token by supplying a crafted X-Grafana-URL request header. This also enables SSRF against arbitrary internal services, including cloud metadata endpoints.	Grafana
CVE-2026-8595	Jul 10, 2026	Grafana Dashboard TableNG XSS via Malicious Field Name A user with Editor permissions can craft a dashboard whose table (TableNG) panel contains a malicious field name that executes as a script in the browser of any user who views the dashboard (stored cross-site scripting).	Grafana
CVE-2026-8609	Jul 10, 2026	Grafana OAuth Login Repeated Calls Causing Unbounded Memory Growth (DoS) An unauthenticated attacker can repeatedly call Grafana's OAuth login route with unique values, causing unbounded memory growth that can eventually exhaust memory and crash the Grafana instance (denial of service).	Grafana
CVE-2026-33382	Jul 10, 2026	Grafana API Unauthenticated Oversize DoS Several Grafana API endpoints, some of them unauthenticated, do not limit the size of the request body before processing it. An attacker can send very large payloads that force excessive memory allocation, potentially exhausting memory and causing a denial of service.	Grafana
CVE-2026-28378	Jul 07, 2026	Grafana Public Dashboard Deletion Endpoint Org Isolation Bypass The public dashboard deletion endpoint does not enforce organization isolation, allowing an Org Admin in one organization to delete public dashboards belonging to a different organization by supplying the target dashboard's identifiers.	Grafana
CVE-2026-42127	Jun 22, 2026	Grafana Public Dashboard Query DoS via Unbounded JSON Size The public dashboard query endpoint does not limit request body size before processing, allowing unauthenticated attackers to trigger excessive memory allocation by sending arbitrarily large JSON payloads. This can lead to denial of service through memory exhaustion. No valid dashboard access token or authentication is required to exploit this vulnerability.	Grafana
CVE-2026-28381	Jun 22, 2026	Grafana Snowflake Datasource GET/PUT Allows Unauthorized File Transfer The Snowflake datasource allows for GET/PUT commands, which can allow any user with access to run queries against the data source to read/write files between the local grafana server and the connected Snowflake host.
CVE-2026-9029	Jun 22, 2026	Grafana Geomap Panel XSS via sanitize-then-interpolate bug A user with Editor permissions can place a malicious script in the attribution field of a Geomap panel's XYZ tile layer via a template variable. The script then executes in the browser of any user who views the affected dashboard (stored cross-site scripting).	Grafana
CVE-2026-10601	Jun 22, 2026	Grafana Tempo/Loki Plugins: Unsanitized URL Path Traversal Exposes Admin Credentials A user with Viewer permissions can use specially crafted requests to the Tempo and Loki data source plugins to reach unintended backend endpoints. Depending on the backend configuration this can expose data source credentials, leak internal responses, or trigger administrative actions on the configured backend.	Grafana
CVE-2026-42129	Jun 22, 2026	Grafana Loki Datasource Plugin Path Traversal (callResource) A user with Viewer permissions can use a path traversal in the Loki data source plugin to reach administrative Loki endpoints and read sensitive backend configuration and internal service information.	Grafana
CVE-2026-27878	Jun 19, 2026	Grafana Tempo TraceQL OOM with Excessive Exemplars Hint A TraceQL query in Grafana Tempo with a large exemplars hint value can cause the Tempo instance to allocate an excessive amount of memory, resulting in an out-of-memory crash. This could allow an authenticated user to trigger a denial of service against the Tempo service.
